Using the Reference Designs & Lab
Setting SAFE & USER Configuration Modes
Before starting board testing in “Testing the Board Using the Factory
Design” , you should have a brief understanding of the two configuration
modes of the Cyclone II DSP development board.
The EP2C70 device on the Cyclone II DSP development board can be
configured by using one of two EPCS64 devices. One EPCS64 device
contains a factory configuration referred to as the “SAFE” configuration;
the other EPCS64 device referred to as “USER” configuration is available
to you to store your custom configuration.
f
Information about SAFE and USER configuration modes is provided in
the Cyclone II DSP Development Board Reference Manual.
■ J29 controls which EPCS64 device to configure.
● Jumper J29, pins 1 and 2 set SAFE EPCS configuration mode to
run the factory design.
● Jumper J29, pins 2 and 3 set USER EPCS configuration mode to
run a user design.
■ The factory design stored on U17 (SAFE EPCS) configures the device
each time the Cyclone II DSP development board is powered up in
SAFE EPCS configuration mode.
You can also reconfigure the device with the factory design stored in
U17 (SAFE EPCS) by pressing SW7, which resets the hardware and
reconfigures the Cyclone II DSP development board in SYS RESET
mode.
c
If you overwrite the factory design stored on U17, refer to the
Restoring the Factory Design appendix in the Cyclone II DSP
Development Board Reference Manual.
■ A user design stored on U36 (USER EPCS) configures the device each
time the Cyclone II DSP development board is powered up in USER
EPCS configuration mode.
For more information on the factory design, and on SAFE and USER
configuration modes, refer to
“Testing the Board Using the Factory
Design” on page 2–15 .
